Each year, long-distance winds drop up to 900 million tons of dust from deserts and other parts of the land into the oceans. Scientists suspect this phenomenon connects to global climate - but exactly how, remains a question. Now a big piece of the puzzle has fallen into place, with a study showing that the amount of dust entering the equatorial Pacific peaks sharply during repeated ice ages, then declines when climate warms.

Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years

Global warming is adding new threats to marine life in the almost land-locked Baltic Sea, where fish are already struggling in polluted, brackish waters, a leading expert said on Wednesday.

New scientific findings are strengthening the case that the oceans and climate are linked in an intricate dance, and that rapid climate change may be related to how vigorously ocean currents move heat between low and high latitudes.

By Jeremy Lovell LONDON (Reuters) - The Atlantic Conveyor, a life-giving ocean current that keeps northern Europe warm, is slowing down, scientists said on Wednesday.

Scientists have long debated what causes glacial/interglacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study finds that these glacial cycles are paced by variations in the tilt of Earth's axis, and that glaciations end when Earth's tilt is large.

ecotone
  • A transitional zone between two communities containing the characteristic species of each.
The word 'ecotone' comes 'eco-' plus a Greek root meaning 'tension'.
